“The article is well worth a read. Author makes the point that all of the “traditional” amphibious capability possessed by China does not equal the effort put forth by the Allies in assaulting Sicily.”
Not only that but new technologies mostly help the defenders. Landing craft are still large, slow moving, and vulnerable.
What’s new is they will have to deal with barrages from shore batteries with far with far greater range, accuracy, and power than those of the 1940s.
Not only what you wrote…but they’ve never done it.
We had Africa and the pacific to learn. The Chinese don’t have that knowledge or logistical experience.
Plus, they won’t be able to hide the buildup.
I would not want to be the tip of that spear.
